SPECIFICATION forming part of Letters Patent No. 631,280, dated August 22, 1899.

I Application filed January 30,1899. Serial No. 703,788. (No model.)

To all whom it may concern;

Be it known that LFREDERIC L. COES, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in the Construction of Wrenches, of which the following, together. with the accompanying drawings, is a speci-' fication sufficiently full, clear, and exact to enable personsskilled in the art to which this invention appertains to make and use the same.

The objects of my present invention are to afford a firm and substantial connection or integration of the ferrule upon the wrench bar or shank and to provide a sectionallyunited ferrule and manner of combining the parts that will facilitate the assembling of the ferrule upon a wrench-bar having a broadened shank in close-fitting relation and with practical convenience and economy in the manufacture.

My improvement consists in constructing and combining the bar-shank and ferrule in the peculiar manner explained in the following detailed description, and illustrated in the drawings, Wherein- Figure 1 represents a side view of the metal parts of a wrench embodying my invention. Fig. 2 is a back view of the handle. Fig. 3 is a side View of the bar-shank. Fig. 4 is a transverse section at line W W, looking downward. Fig. 5 is a section at line X X, looking upward, the two parts of the ferrule being shown separated. Fig. 6 is a central vertical section of the two separate parts of the ferrule. Fig. 7 is an inner side elevation of the front section of the ferrule, and Fig. 8 is an inner side elevation of the back section of the ferrule.

In referring to the drawings, A denotes the wrench-bar, having the usual fixed jaw thereon and supporting the movable or sliding jaw B, which is controlled and operated by the adjusting-screw C and its rosette C arranged thereon in well-known manner. The bar-shank A below its neck D is flattened and broadened or spread to the full width of the handle and made as a plate-like frame for receiving the wooden scales or side pieces E, which give fullness to the handle. The bar is formed with shoulders on its front and back edges at the top end of the handle and at the lower end of the ferrule' F indicates the ferrule, which in accordance with my invention is divided longitudinally or made in two parts-a front part or section F, having the step-bearing f for the rosettescrew pintle formed thereon, and the backwardly-directed sides or cheeks 3 3, between which there is a central space 77., dressed out for receiving and fitting the neck D of the bar,-and a back part or section F formed, as shown, with inner space E to fit the bar, and cheek portions 5 5. The end surfaces of the checks 5 are fitted to oppositely countermatch against the ends of the cheek portions 3 3 of the front part F at line on when the parts are assembled, thus completing the full circle of the ferrule. Each part of the ferrule has a leg or downward extension F and F the inner face of which is in the same plane with the inner or neck-matching surface, and the projecting side lips 6 are integrally formed on said extensions, as shown. The sides of the ferrule are under-recessed, as at e, to receive the tenon e on the wood scales or handle-plates E.

The bar-shank A is primarily made straight in continuation of the bar. Then after the sliding jaw B is placed thereon the shank is swaged to give it greater width or flattened and spread laterally into the form of a fiat plate having the general outline contour of the handle along its front and rear edges h h, as indicated in Fig. 3,, and the tip-flanges t are formed on its end. The surplus metal at the upper part of the spread shank is then cut away at i i, forming the'neck D of a width and dimension that will fit the inner space it n of the two unitable parts of the ferrule and producing the lower shoulders I I on the edges of the shank and the upper shoulders 01 at the point where the bar enters the handle. The shoulders I and I are preferably made square, but can be somewhat inclined or dovetailed, if in any instance so desired. The length of the recessed sides z' i of the bar-shank corresponds with the length of the ferrule F with its extending legs F F After the shoulders I I and neck D have been properly formed the two parts of the ferrule F are put on, the sections F and F being inserted transversely from opposite sides. The part F, with the rosette C centered in the step fand with the end of the screw 0 entered in the end of the sliding jaw B, is assembled upon the front i of the bar-neck, and the part F is assembled on the back 1" of the neck, the sides 3 and 5 coming together at the line m. The parts of the ferrule are then integrated with each other by a fused metal joint at m and with the neck and edges of the barshank, as by brazing together the adjacent surfaces, thus permanently uniting the two parts of the ferrule at their counter-matched sides, and solidly attaching the innersurfaces of the ferrule and its extended legs to the bar-shank edges 2' i and shoulders I I and d, producing an absolutely integral and rigid union of said parts.

Vhen it is desired to make a very close joint at the junction of the ferrule-leg and the shoulder I or I, the metal of the edges of the bar-shank can be given a little fullness adjacent to the shoulders, as indicated by dotted line at J on Fig. 1, and the angle at that point then hammered down after the ferrule-section has been inserted, thereby closing the abutting shoulder more closely against the end of the ferrule-leg previous to the brazing of the parts.

The side plates E may be fitted to the flat barshank A and retained by an end tenon e and by the transverse rivet r in usual manner.

The feature of forging a wrench-bar shank in a manner to flatten and broaden the same into a plate-like form and outline contour for the handle after the sliding jaw has been assembled upon said bar has been made the subject of or described in prior Letters Patent. Hence it will be understood that my invention is not broadly for the broadening of the shank, but has reference to the manner in which the ferrule is constructed andcombined with the bar-shank in the production of a wrench, substantially as described.

I claim as my invention- 1. A wrench comprising a bar having a fixed jaw, a movable jaw sliding on said bar,

and a screw controlling the adjustment of said movable jaw; the shank portion of said bar swaged to greater width than the bar proper and provided on its front and back with upper and lower shoulders, a collar or ferrule composed of two counter-matching sections, one of which is provided with a projecting step for supporting the end of said screw, said ferrule-sections fitting between the upper and lower shoulders respectively upon the front and back edges of the shank, the coun oer-matching surfaces of the two sections abutting upon each other at the sides of the bar, and permanently secured together by a fused metal joint, substantially as set forth.

2. In a wrench, alongitudinally-divided ferrule formed in two transversely-i nsertible sections, one section provided with the screw-sup porting step; in combination with the wrenchbar, the sliding jaw, and rosette-headed adjusting-screw; said wrench-bar having a broadened swaged shank, its neck fitted with recesses and shoulders on the opposite edges thereof, for receiving and supporting the ferrule, and into and against which the respective ferrule-sections are applied, substantially in the manner set forth.

3. In a wrench of the character described,

the ferrule composed of the separately-formed transversely-unitable parts or sections, each provided with a downwardly-extended leg; in combination with a wrench-bar providedwith a broadened and flattened shank conforming to the handle outline, and having at its front and rear edges recesses and shoulders abutting against the end of said legs, said ferrulesections oppositely inserted transversely into the recesses on theneck of the bar and against said shoulders, the two parts of the ferrule permanently integrated together and to the bar by brazing, substantially as set forth.

\Vitness my hand this 23d day of January, 1899.

FREDERIC I1. GOES.
